I am updating the stereo system in my new to me 1998 Caravelle 188. I got a new Kenwood HU to power one pair of 6.5 and one pair of 5.25 Kicker Speakers. A 4ch 600w amp will push a pair of Alpine 6.5" components off two channels and a 10" Kicker Comp sub in a ported box bridged from the other two channels That should give me 100X2 and 250X1 off the amp. Does this sound like a good set-up...the only item I don't currently have is the amp. Of all the ones I have looked at I think this would be a good, simple system that should sound great.
